Well i just moved the tuner card down a couple of slots, and now the idle temps are showing about 3c cooler, which is an improvement, but still i think too hot....i currently have 2 80mm fans (pretty bad ones though lol)...one is on the side of the case, the other at the back..my stupid case doesn't have room for one at the front, which im a bit peeved at...how should i have the 2 fans i have blowing, and ill look into those PCI things, they look sound cool

No, it shouldn't. The fan from the GPU is doing it's thing pushing the air out while the PCI exhaust blower is picking up warm air from the leftover heat of the video card and around it's immediate area. It doesn't make it worse, let's put it that way.

It should be ok. I mean those video cards are suppose to handle 100+ degreec Celsius. When you go into the Nvidia display properties and look at the GPU temp, it should tell you what the temperature threshold is. Mine says 110 degrees which is the max. I'm running around 42 degrees right now, but that's because I'm not doing anything either. When you play games, it's normal to be that high. I was playing Medal of Honor one time and it shot up to 80 degrees. But once I stop it, you can see the temps climb down to it's normal range.
